Unit #3 at Neil Denari’s iconic HL23 is one of only two duplexes in the building with private outdoor space—the other being the Penthouse. This striking 2,044 square foot residence offers two bedrooms and two and a half baths. Both the primary ensuite and second bedroom face south. The upper level features an open kitchen and dining area that overlooks a dramatic square living room with 19-foot ceilings, a wall of glass, a half bath, and access to a private 711 sq ft outdoor terrace. Thoughtfully designed throughout, the home showcases oil-finished, custom-stained solid oak flooring, Nanz hardware, recessed base moldings, and Aprilaire temperature sensors with remote thermostat. The sleek kitchen is outfitted with custom-built Poliform cabinetry, Corian countertops, and top-of-the-line Miele appliances. Spa-quality bathrooms include Paonazzo marble slab walls, integrated Corian vanities, a Boffi Swim soaking tub, and radiant heated floors in the master. Sustainably built, HL23 is targeting LEED Gold certification. The building draws 100% of its energy from green power and exceeds indoor air quality standards by 30% through enhanced ventilation and low-VOC materials. High-efficiency water fixtures cut consumption by over 30%, while integrated mechanical systems and a tight envelope reduce energy use by 15–25%. Abundant natural light minimizes the need for artificial lighting, and reflective roofing helps counter the urban heat island effect. Over 75% of construction waste was diverted from landfills, with extensive use of recycled materials. Additional eco-conscious features include bicycle storage to encourage zero-emission transportation. Building amenities include a 24-hour doorman and a 900-square-foot fitness center. Located in the heart of West Chelsea—home to top art galleries, the High Line, renowned dining, and cutting-edge boutiques—this residence offers a truly unparalleled urban lifestyle.
